OpenAI models: common questions

How many AI models has OpenAI released?

ModelCap tracks 64 canonical OpenAI models as of 6 November 2026: 59 language models (21 with a public ModelCap Index position) and 5 image, audio or video models. Superseded versions and equivalent serving routes stay listed on this page, marked as such.

What is the best OpenAI model?

GPT-6.1 Sol Pro is OpenAI's highest-ranked model as of 6 November 2026, at ModelCap Index position #7 with a score of 82.1, followed by GPT-6.1 Sol (#8). The table lists every ranked OpenAI model in Index order.

What is the cheapest OpenAI model?

gpt-oss-120b at $0.09 per 1M output tokens ($0.024 per 1M input) as of 6 November 2026, the lowest listed price among OpenAI's 50 priced language models. Prices are the lowest current provider offer on the OpenRouter catalogue.

Which OpenAI model has the largest context window?

GPT-6.1 Sol Pro, with a published context window of 1M tokens. Individual providers can serve less than the published maximum; each model page lists every endpoint's own limit.

Are OpenAI models open-weight?

5 of 64 tracked OpenAI models publish downloadable weights (open weights). ModelCap labels weight availability from repository metadata, not whether the training stack is open source; the licence class is shown beside each row.

What is the newest OpenAI model?

GPT-6.1 Terra Pro, first listed on 26 October 2026. New OpenAI models appear here as soon as they pass automatic identity checks; the launches page tracks releases across every publisher.
